我需要查看我的Android应用程序的互联网消费情况.在我的应用程序中,我调用了大量的Web服务API.

我想知道我的应用程序在完整的时间内以KB/MB的速度消耗互联网的​​程度.

我该怎么检查？有没有工具来检查？

我最近将我的工作室更新为北极狐，但我的项目出现错误

A problem occurred configuring root project 'so10'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Using insecure protocols with repositories, without explicit opt-in, is     unsupported. Switch Maven repository 
'maven3(http://oss.sonatype.org/content/repositories/snapshots)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols.
 See https://docs.gradle.org/7.0.2/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.

我正在尝试从服务中下载图像并将其显示在活动中,但我一直在努力

在我的应用程序中,我需要检查WiFi和移动数据的连接速度,然后比较它,然后切换到哪个网络具有最高的速度.

• 那么如何才能获得wifi和移动数据的速度或最佳信号强度？
• 如何以编程方式关闭一个和另一个.

请帮帮我.样本会有所帮助.

我正在使用Android工具栏.我只想更改溢出菜单的背景颜色.但它并没有改变.

我最近将我的 android studio 更新到版本 - 2021.2.1 Patch 2\n我的 gradle 分发版本是7.3.3

当我构建项目时，出现以下错误

我想在我的应用程序中从原始mp3或wav文件设置自定义通知声音.以下是我的代码
